Date before 30 days

Question

Hi,
I have CURRENT DAY variable and i want to create one more variable which gives the Date before 30 days.
Is there any STD variable which gives the date before 30 days .Please tell me.
I have created one variable with Customer exit processing type and i need to develop code for this. Can anybody provide code how we will get date(dd/mm/yyyy) before 30 days .I have created variable with name "Z_CVAR". Please help me on this.

Answer 1

use 0date variable to get the system date ... which is the SAP standard variable which pics the sy-datum.
Next restrict the KF with the 0date and right click on the 0date and click on offset and set the off set for the varaible as -30.
which gives the value -30 days.
If not as suggested in the earlier post -- create a z variable with replacement path -customer exit -- write the code ... in the code itself write the logic to get the -30 days
IF i_step = 2.
CASE i_vnam.
WHEN 'ZCURDAY-30'.
CLEAR: l_s_range.
l_s_range-low = sy-datum -30.
l_s_range-sign = 'I'.
l_s_range-opt = 'EQ'.
APPEND l_s_range TO e_t_range.
ENDCASE.
ENDIF.
regards
